I found a solution for the problem.
I've forgotten to change the video bitrate.
I had it at 1008 and that's to high for the ds.
I'm using tuna-viDS only as plug-in for moonshl2.
I get very much errors at encoding with dpgenc.

indiana jones one is just about 100mb big on my ds,I think that's small compared to my other videos(one south park episode in dpg is 60mb,and they're just 20 minutes long!).
and with my settings in super it has also somehow good quality.
The only bad thing is that you have to turn off your ds when when the video ends nd can't get back to moonshell.
